ABSTRACT:
An apparatus for administering parenteral liquids from a parenteral fluid container which provides a sufficient quantity of parenteral liquid to be administered at a slower than normal rate so as to afford a keep-vein-open (KVO) means. The apparatus utilizes a first orifice to afford a faster flow rate than a second orifice spaced away from the first orifice. The preferred means for regulating different flow rates of fluid through the two orifices are the dimensions of the orifices and filters having different mesh sizes. When the parenteral liquid is maintained in the reservoir in contact with the first orifice with the faster flow rate, liquid will pass through both orifices at a predetermined regular rate. When liquid no longer contacts the first orifice, as when the fluid container is depleted of liquid, the second orifice then comes into effect to afford a slower rate of liquid until a new container can be supplied.
